Pad Controller xbox360 - triggers

Hello,

I've been adding pad controll to my game. I was able to configure both analogs and all buttons that are avaiable in pad fox xbox360, but one - triggers axis. I have read that they axis #3 (both) or on two different axis (LT #9, RT#10).

Tried both possibilities - none worked for me. Here's how I configure my Input:

And below is my code that I check my inputs with:

 if((Input.GetAxis("PAD_Trigger")) != 0)
 {
       Debug.Log("Trigger used");
  }
